USC-Nebraska: What is "disconcerning?"

NU just went on a 10 play, 52-yard drive to make this a 7-7 game with a minute left in the 1st quarter on a one-yard dive by Cody Glenn.

After setting up for a field goal and getting flagged for something the ref called "disconcerning" the Huskers punched the ball into the end zone two plays later

Guess that means the SC defense was imitating the "hut-hut" of the offense. And let me say, although I'm back up in the whisper-quiet press box, the stadium sounds a bit louder now. That will obviously help NU if they stick around in this game.
